In order to better understand intricate operations and detailed planning needed to capture multi-ton boulder from asteroid surface
Space news (Asteroid Redirect Mission: testing of prototype of robotic capture module system) – The Robotic Operations Center of NASA’s Goddard Space Flight Center –
Inside the Robotic Operations Center (ROC) of NASA’s Goddard Space Flight Center engineers are at work preparing the robotic section of the Asteroid Redirect Mission (ARM). The most recent work involved testing a prototype of the asteroid capture system with a mock boulderbuilt by NASA and students from West Virginia University. This work will help engineers learn more about the intricate operations needed to capture a multi-ton boulder from the surface of an asteroid. The robotic section of ARM is targeted for a 2021 launch window.
The capability built into the ROC allows engineers to create a simulation of the capture of a boulder from the surface of an asteroid. Here they can also simulate servicing of the satellite, fine tuning of systems and controllers, and even optimize all performance factors for future repairs and refueling. An important capabilitywhen building spacecraft worth hundreds of millions of dollars and even more. One that saves money and time.
The report reflects the findings of a two-month study conducted by members of the Small Bodies Assessment Group (SBAG). It explains many of ARM’s potential contributions to the future of the human journey to the beginning of space and time.
“This report is an important step in identifying ways that ARM will be more scientifically relevant as we continue mission formulation for the robotic and the crew segments,” said Gates. “We’re currently in the process of selecting hosted instruments and payloads for the robotic segment, and hope to receive an updated analysis from the SBAG after we announce those selections in spring 2017.”
By passing historic legislation H.R. 2262 into law
Space news (November 17, 2015) – U.S. House of Congress –
When President Abraham Lincoln signed the Homestead Act into law on May 20, 1862, this spurred growth in the search for gold and timber to fuel the expanding economy of the nation and opened up new frontiers for continued growth and prosperity for all.
Now, all Americans can take part in the future asteroid bonanza on the space frontier in the decades ahead.
On November 10, 2015, U.S. Congress passed into law bill H.R. 2262, legislation recognizing the right of Americans to own the resources contained within asteroids they claim as property.
“We are proud to have the support of Congress. Throughout history, governments have spurred growth in new frontiers by instituting sensible legislation. Long ago, The Homestead Act of 1862 advocated for the search for gold and timber, and today, H.R. 2262 fuels a new economy that will open many avenues for the continual growth and prosperity of humanity. This off-planet economy will forever change our lives for the better here on Earth,” said Chris Lewicki, President, and Chief Engineer, Planetary Resources, Inc.
“Planetary Resources is grateful for the leadership shown by Congress in crafting this legislation and looks forward to President Obama signing the language into law. We applaud the members of Congress who have led this effort and actively sought stakeholder input to ensure a vibrant economy and prosperous way of life now and for centuries to come. Patty Murray (D-WA), Kevin McCarthy (R-CA), Lamar Smith (R-TX), Bill Posey (R-FL) and Derek Kilmer (D-WA) have been unwavering in their support and leadership for the growth of the U.S. economy into the Solar System. Their forward-looking stance and active role in enabling the development of an economically and strategically valuable new marketplace will ensure our country’s continued leadership in space,” said Peter Marquez, Vice President of Global Engagement, Planetary Resources, Inc.
In the words of Senator Murray, “I am glad that we’ve taken this important step forward to update our federal policies to make sure they work for innovative businesses creating jobs in Washington state. Washington state leads in so many ways, and I’m proud that local businesses are once again at the forefront of new industries that will help our economy continue to grow.”
Congressman Posey said, “This bipartisan, bicameral legislation is a landmark for American leadership in space exploration. Recognizing basic legal protections in space will help pave the way for exciting future commercial space endeavors. Asteroids and other objects in space are excellent potential sources of rare minerals and other resources that can be used to manufacture a wide range of products here on Earth and to support future space exploration missions. Americans willing to invest in space mining operations need legal certainty that they can keep the fruits of their labor, and this bill provides that certainty.”
Congressman Kilmer said, “The commercial space industry in Washington state is leading the way in developing the cutting edge technology necessary to support human space exploration. The U. S. Commercial Space Launch Competitiveness Act will give these ventures the framework they need to continue to innovate and to keep the United States at the head of this growing, global industry. I congratulate the Senate for taking this step, and I look forward to the House quickly sending this bill to President Obama’s desk.”
Eric Anderson, Co-Founder, and Co-Chairman, Planetary Resources, Inc., said, “Many years from now, we will view this pivotal moment in time as a major step toward humanity becoming a multi-planetary species. This legislation establishes the same supportive framework that created the great economies of history, and it will foster the sustained development of space.”

Just add water, gasses, and simple organic molecules
Space news (July 27, 2015) – the search for life beyond Earth – a simple recipe for extraterrestrial life –
NASA scientists studying the origins of organic compounds important to the development of life on Earth think they’re on the trail of a cosmic “Crucible of the Building Blocks of Life”. Recent experiments conducted by astrobiologists working at the Goddard Space Flight Center in Greenbelt, Maryland indicate asteroids and meteorites could have been the source of complex organic compounds essential to the evolution of life on Earth. Essential organic compounds they have been able to reproduce in laboratory experiments from simpler organic compounds, water, and gasses in simulations of the space environments of meteorites and asteroids.
“We found that the types of organic compounds in our laboratory-produced ices match very well to what is found in meteorites,” said Karen Smith of NASA’s Goddard Space Flight Center in Greenbelt, Maryland. “This result suggests that these important organic compounds in meteorites may have originated from simple molecular ices in space. This type of chemistry may also be relevant for comets, which contain large amounts of water and carbon dioxide ices. These experiments show that vitamin B3 and other complex organic compounds could be made in space and it is plausible that meteorite and comet impacts could have added an extraterrestrial component to the supply of vitamin B3 on ancient Earth.”
“This work is part of a broad research program in the field of Astrobiology at NASA Goddard. We are working to understand the origins of biologically important molecules and how they came to exist throughout the Solar System and on Earth. The experiments performed in our laboratory demonstrate an important possible connection between the complex organic molecules formed in cold interstellar space and those we find in meteorites.”
The Crucible of the Building Blocks of Life
Deep within immense clouds of gas and dust created by exploding stars (supernovae) and the winds of red giant stars coming to the end of their days are countless dust grains. Many of these dust grains will end up part of asteroids and meteorites like the millions of bodies in the Main Asteroid Belt, Kuiper Belt, and Oort Cloud. Asteroids and meteorites that bombarded the Earth from space during the formation of the planets and Solar System.
NASA space scientists were able to reproduce a “Crucible of the Building Blocks of Life” using an aluminum plate cooled to minus 423 degrees Fahrenheit (minus 253 Celsius) as the cold surface of an interstellar dust grain carried by an asteroid or meteorite heading to Earth 4.5 billion years ago. The experiments were conducted in a vacuum chamber used to replicate conditions in space to which they added gasses containing water, carbon dioxide, and the simple organic compound pyridine. Bombarding the cold surface with high energy protons from a particle accelerator to simulate cosmic radiation and other radiation found in space produced more complex organic compounds like vitamin B3.

Structures created during cataclysmic collisions between objects left over from planet formation or something unknown?
Space news (July 13, 2015) – collisions indicating possible gravitational effects of unseen orbiting exoplanets or consequences of the star traveling through interstellar space –
Space scientists using the Hubble Space Telescope recently completed a visible-light imaging survey of the debris field systems around 10 young stars between the ages of 10 million to 1 billion years old. Debris fields they studied in order to better understand the early solar system and formation of the planets.
“It’s like looking back in time to see the kinds of destructive events that once routinely happened in our solar system after the planets formed,” said survey leader Glenn Schneider of the University of Arizona’s Steward Observatory.
What did the survey find?
Space scientists studying the evolution of stars and the formation of planets used to think debris fields surrounding young stars should be composed of simple pancake-like structures.
The complexity and diversity in debris fields studied in this recent survey strongly suggest this scenario is a little more involved than theories suggest. Facts indicate the possibility of gravitational effects of unseen exoplanets hidden within the dusty debris, the results of the young star traveling through interstellar space, or something unthought of as the reason for the deviation from theory.
“We find that the systems are not simply flat with uniform surfaces,” Schneider said. “These are actually pretty complicated three-dimensional debris systems, often with embedded smaller structures. Some of the substructures could be signposts of unseen planets.” The astronomers used Hubble’s Space Telescope
Imaging Spectrograph to study 10 previously discovered circumstellar debris systems.
Star HD 181327 Shows Huge Debris Spray
The ring-like debris system surrounding star HD 181327 has irregularities space scientists think could be due to a recent collision between two bodies on the outer part of the system.
“This spray of material is fairly distant from its host star — roughly twice the distance that Pluto is from the sun,” said co-investigator Christopher Stark. “Catastrophically destroying an object that massive at such a large distance is difficult to explain, and it should be very rare. If we are in fact seeing the recent aftermath of a massive collision, the unseen planetary system may be quite chaotic.”
“Another interpretation for the irregularity is that the disk has been mysteriously warped by the star’s passage through interstellar space, directly interacting with the unseen interstellar material. “Either way, the answer is exciting,” Schneider said. “Our team is currently analyzing follow-up observations that will help reveal the true cause of the irregularity.”
As of 07/09/2015 space scientists have verified the existence of 1858 exoplanets, including 468 exosolar systems with multiple planets, and 92 Earth-size terrestrial-type planets. The structure and overall architecture of the systems discovered so far are more diverse than astrophysicists first proposed.
During this time, space scientists have only viewed about two dozen light-scattering, circumstellar debris systems due to their comparative faintness and proximity to their parent stars. Despite the small sample size in exoplanetary debris systems astronomers view a surprising variety of architectures.
“We are now seeing a similar diversity in the architecture of the accompanying debris systems,” Schneider said. “How are the planets affecting the disks, and how are the disks affecting the planets? There is some sort of interdependence between a planet and the accompanying debris that might affect the evolution of these exoplanetary debris systems.”
Space scientists will now use the results obtained through this survey and the overall study of the debris system disks viewed to devise new theories and experiments to determine more about the evolution and growth of young stars in the cosmos.
They’ll also use the data and information gained to begin looking at how our solar system formed and evolved during the past 4.6 billion years. They want to study collisions between objects like HD 181327 and Earth-like planets to give more insight into the birth and evolution of our planet and the Moon during the first moments of the solar system.

Space & Astronomy Wiki – the planets in the solar system –
At an average distance of 0.72 AU from Sol, Venus is the second planet from the Sun, closest sister planet to Earth in size and mass, and the third densest planet in the solar system at an average density of 5.24 g/cm3.
The second-brightest object in the night sky, with the Moon being the brightest, at between magnitude -3.8 and -4.6, Venus was first recorded by Babylonian astronomers in the 17th century BC and is named after the Roman Goddess of Love and Beauty.
Called both the Evening Star and Morningstar, Venus is the second largest terrestrial planet in the solar system and the hottest planet with an average surface temperature of 462 degrees Celsius.
Composed of a crust, molten mantle, and core, the surface of Venus is totally obscured by dense clouds of carbon dioxide that trap heat very effectively, producing a runaway greenhouse effect.
Rotating very slowly on its axis, Venus rotates in the opposite direction to the other planets in the solar system, creating extremely long days and nights, and a west to east movement of the Sun across the sky.
Looking at the surface of Venus you see mountains, valleys, craters, and even evidence of previous volcanic activity. This is deceiving, though, because the geology of the surface of this planet is very different than that of Earth.
We’ll talk more about the surface geology, atmosphere and life history of Venus in future articles.
Space news (astronomy leaders of tomorrow: The International Astronomical Search Campaign)
An asteroid is a piece of solid rock with an irregular body ranging in size between 500 meters and hundreds of kilometers. The majority of these bodies can be found in the main asteroid belt, a region of space between Mars and Jupiter. Pieces of rocky material left over from the formation of the solar system over 4.6 billion years ago, NASA scientists estimate there are as many as 40,000 asteroids contained within this main asteroid belt, with a combined mass less than the Moon. Confirming the identity and calculating the orbit of the asteroids contained within this belt is part of the space mission of NASA’s Wide-Field Infrared Survey Explorer (WISE).
The International Astronomical Search Campaign (IASC) is an educational outreach program created to allow high school and college students around the country to participate in identifying and calculating the orbit of every rocky body within the main asteroid belt. Originally created and developed by Patrick Miller of Hardin-Simmons University in the state of Texas, this program has helped tens of thousands of students in 250 schools and 25 countries on five continents learn more about astronomy.
Students participating in the program download images taken of an asteroid within the main asteroid belt in the last few hours by telescopes (24 and 32 inches) located in the Astronomical Institute in Illinois. Students must determine the identity and calculate the three-dimensional orbit of an asteroid using Astrometrica, a software package users need to download directly from the IASC website, within a three-day window.
The telescopes take three images of an asteroid at six-minute intervals, which means it would have moved around five pixels in relation to distant background stars in each image. Astrometrica highlights objects in each image fitting these criteria by putting a red circle around them.
In order to determine an object is an asteroid, students must sort through objects that have moved in the images, and ones that are static. They do this by taking a look at the fit of the point spread function, the signal-to-noise ratio, and any change in the size of an object in the images. If an object has moved in a relatively straight line, stayed about the same size, has a signal-to-noise ratio greater than five, and is approximately round in shape, then it’s probably an asteroid.
Join the human journey to the beginning of space and time today!
A typical International Astronomical Search Campaign lasts about 45 days, during which new asteroids are often discovered, identified, and their orbits determined. This is your chance to become an astronomy leader of tomorrow, by participating in the International Astronomical Search Campaign, and WISE’s mission to identify and calculate the orbit of every rocky body in the main asteroid belt.

Watch for a ghostly glow rising from the corpse of streaking meteorites once they pass
Space news – October (2014) –
This Halloween modern sky watchers in both hemispheres have the opportunity to witness a ghostly celestial phenomenon viewed by ancient astronomers for generations, the ghostly afterglow of streaking meteorites of the Orionid meteorite shower. For a few nights centered on October 21, 2014, you can watch for a ghostly glow rising from the corpse of each streaking meteorite, which is pieces of Halley’s Comet burning up as they pass through Earth’s atmosphere.
E.C. Herrick is thought to have made the first modern sighting of the Orionid meteorite shower between 1839-40, but his measurements and data were imprecise. The first pinpoint study of this meteorite shower is credited to noted astronomer A.S. Herschel on October 18, 1864, when he recorded 14 meteorites appearing to originate from the constellation of Orion, but it would take a further year of study to confirm his findings.
During the 19th century, British astronomer W.F. Denning and American astronomer C.P. Olivier had a documented debate about whether the point from where the meteorites appear to originate moved from night to night. It would take until the 20th century for modern space scientists to determine using state-of-the-art photography and precise plotting of Orionids that this is in fact not true.
W.F. Denning published a report in one 1887 issue of The Observatory, in which he stated he saw 47 of 57 streaking Orionids leave a ghostly glow in their path after passing, during a viewing session lasting five nights. Denning estimated the magnitudes of streaking Orionids’ between 2nd and 4th magnitude, due to several that brightened considerably after burning up. Watch carefully on the nights centered around October 21, 2014, and you could witness this ghostly celestial phenomenon for yourself.
The best part of viewing Orionids is you don’t need technology because human eyes are perfect for the job. The Moon will be almost new this October, so just find the best spot to view the night sky you know, and lie down on a soft spot on the ground. The best time to arrive for the show is just before midnight or just prior to dusk, but any time between 12 and dawn should be fine. Viewers in the Southern Hemisphere should look towards the northeastern sky, while people in the Northern Hemisphere should look towards the southeast.
Get out there and view the cosmos
Serious sky watchers desiring to get a better idea of the exact times and dates during October 2014 to view Orionids where they live, can get a better estimate here. Just remember to check weather forecasts for the October nights you plan on viewing the night sky for Orionids and dress accordingly. If everything goes as predicted this Orionid meteorite shower could provide as many as 20 opportunities an hour to view a ghostly glow rising from the corpse of a streaking meteorite.
Space news (the solar system: comets and asteroids; Comet 209P/LINEAR)
Debris ejected from Comet 209P/LINEAR during the 18th – 20th centuries could lighten the skies in southern Canada tonight. Expectations are for a possible Camelopardalis meteorite shower between 2 – 4 a.m EST tonight. Astronomers aren’t really sure if the show will be spectacular or a small production. In fact, they don’t have any data indicating how active the comet was during the past two centuries when the comet’s debris tails are believed to have been created.
The show could be one to forget or unforgettable, it all depends on a lot of factors. As the Earth passes through the debris field of Comet 209/P LINEAR tonight, small pieces of dust and particles could be released into the atmosphere that will create bright streaks of light we call meteorites. Estimates run as high as 200 meteorites per hour are being thrown around, which is 100 meteorites higher than the Perseids and Leonids in November. This could probably best be termed a meteorite storm, rather than a shower, and the true number could be even higher.
The best time to view the Camelopardalis meteorite shower is 12 midnight May 24, 2014, but I suggest you get there early. The shower will occur through a very narrow window of opportunity for viewers in southern Canada if we get a show to see. You won’t need to use binoculars or a telescope, just bring a blanket to lay on or chair to sit in, and something to warm the stomach.
Pick the darkest spot you can conveniently reach and you should be able to see even faint meteorites, which are probably unassociated with the Camelopardalis meteorite shower. White light will destroy your natural night vision, which will take 15 to 30 minutes to return. This includes light sources like cell phones and flashlights unless the light is red, so keep this in mind.
Look toward the Big Dipper and find the last star from the spoon. Just follow this star toward the first bright star you see. This star is Polaris and the constellation Camelopardalis, the area of the sky where the Camelopardalis meteorite shower originates, is near this star.
The most important thing to remember is to look upward during the window of opportunity. Many viewers forget to follow this simple tip and miss part, or all, of the meteorite show.
Astronomy questions and answers – 2014 is expected to be a banner year for the human journey to the beginning of space and time. This year we are treated to a total eclipse of the Moon for the first time since December 2011. Find a good viewing spot on the night of April 14/15 and watch as the Full Moon falls far into the Earth’s shadow. Skywatchers and astronomers across North America can watch the entire show from the comfort of their favorite dark sky viewing spot. The partial phases of the eclipse will get started around 1:58 a.m. eastern standard time. Watch during the next hour, or so, as the Moon darkens as totality nears. Totality lasts from about 3:06 to 4:25 and the Moon should look orange-red during this period as sunlight filters through the Earth’s atmosphere. The show should finish around 5:33 a.m, with a wrap up of the partial phases.
The Moon once again falls into the Earth’s shadow on the morning of October 8, 2014. The partial phases of this celestial event get started around 5:14 a.m. eastern standard time, with totality occurring at 6:24 a.m. The Moon will spend about an hour immersed in the shadow of Earth, before reappearing like a phantom at 7:24 a.m. Skywatchers and astronomers located in western North America will have the best seat for the show while people on the East Coast will get a partial show.
No total eclipse of the sun in 2014
There will be no total eclipse of the sun during 2014, but on the afternoon of October 23 skywatchers and astronomers across North America will be treated to a partial eclipse of the closest star to Earth. Viewers in the majority of the United States of America should see the Moon block over 40 percent of the Sun’s disk from view while people in the northern states and lower Canada should see the Moon cover over 60 percent. The best view of this partial solar eclipse will be in the far northern regions of Canada, with about 81 percent coverage of the Sun’s disk.
Planet hunters should enjoy the show during 2014
Planet hunters can book a seat for the dramatic appearance of Mars in the sky during spring of 2014. The Red Planet reaches opposition April 8, and will shine at magnitude -1.3 and appear big (15”) and bright when viewed through a telescope. Mighty Jupiter reigns supreme in the sky during the month of January 2014 and will peak early during this month. Saturn will also be spectacular to view both a few months before and after opposition on May 10, 2014, while beautiful and serene Venus will dazzle skywatchers before dawn during late winter and spring.
Meteorite hunters look forward to potentially great 2014
Meteorite hunters can also look forward to a potentially great year of viewing one their favorite celestial bodies. Viewers planning to look at the Perseids during August will have to deal with the light from a Moon which will be almost full, but people watching the Quadrantids during January won’t have to deal with much light from this source. The other expected meteorite showers during 2014 should all be free from interfering light from the moon. All-in-all 2014 should be a memorable year for astronomers and backyard skywatchers taking part in the human journey to the beginning of space and time.
Astronomy News – It was a typically slow Friday morning for workers in the Russian industrial city of Chelyabinsk just east of the Ural Mountains. Just after 9 a.m. Russian time, the Sun was hanging just above the horizon to the southeast. The air was cold and still and the sky clear; accept for a few high clouds, and contrails from passing jets.
The quiet morning would explode with the arrival of an unexpected guest. A significant lightening of the sky toward the rising sun was the first hint something was different. Seconds later light exploded in a blinding flash that moved across the sky from right to left. The ground seemed to rumble and rotate in time with naked shadows of buildings, cars, and lampposts.
The blinding glare from the smoking object started to subside as its smoke trail broke into two parallel smokers moving across the southern sky. The sky flared twice more in blinding flashes of intense light, before the objects disappeared over the southwestern horizon.
Shockwave impacts the ground
Three to four minutes after the blinding flash came streaking across the sky, a colossal tremor hit the region shattering windows and causing car alarms to blare and humans to cry and exclaim. Incredibly, no loss of human life would result from the event, although over 1,000 people were treated for related injuries.
NASA has coined the term “superbolide”, for the dazzling bolide that resulted from the passage of a meteorite through the Earth’s atmosphere on February 15, 2013. The meteorite travelled through the atmosphere at a shallow 7 degree descending angle from east to west that passed about 12 miles (20 km) south of Chelyabinsk, Russia. The superbolide occurred when the meteorite was at an altitude of around 76,400 feet (23,300 meters) and moving at a speed of 11.6 miles per second (18.6 km/s).
Force of friction between the atmosphere and meteorite slowed and heated it. The fast movement of the meteorite through the atmosphere also compressed the air in front of it, creating the colossal tremor that shattered windows on the ground. The compression also ionized atoms and molecules, which emitted the blinding flash seen in the Russian sky, when they recombined with the electrons that were stripped from them. This energy also broke up the meteorite and ultimately caused it to explode when the increasing internal pressure exceeded the object’s internal strength.
